Sangoma A200 wt HW echo on 64bit Centos , 4 fxo and crosstalk!
Hi,
Has anyone ever experienced crosstalk with sangoma analogue cards on 64bit?
We have exhausted every test to try and replicate this and find a
solution with Sangoma tech support, but we can not fix it.
We are about to try the card and four *seperate* UK BT lines in a 32bit system.
The current system is a 4gb, dual core cpu with pbx in a flash 1.4,
Zaptel and Asterisk 1.4.21-2

Help forcing crosstalk
Hey List-ee's!
We're on Asterisk 1.2 with a PRI/T1 and maybe 50 phones.
Issue: When a conference is ongoing (meetme), if a call is placed to a PRI #
(CALLER A) the audio from the conference is heard by that caller while the #
they dialed is ringing in the background. The opposite also occurs where an
outside caller will be heard in the conference channel as well.
Frequency: 2-3 times

FEC and Stereo
Hi,
One other question I was wondering about. Is the reason that we hear the crosstalk with fec and packet loss percentage>0 is that Opus uses information from the left channel to try to error correct the right channel and vice versa? I am trying to understand the origin of the crosstalk.
Thanks.

Not necessarily. Stereo makes two assumptions:
1) It assumes the two channels are somehow correlated
2) It assumes the two channels are meant to be

Correct. Another effect I forgot to mention is that Using FEC will
actually force SILK/hybrid rather than CELT, so it's possible that
disabling FEC makes you use CELT, which

Thanks.
When you say that with fec enabled, the threshold is increased, do you mean the bitrate - i.e., you need higher bitrate with fec enabled to suppress crosstalk?
Also, can you make any recommendations to decide whether to use fec or not? We are trying to tune the parameters appropriately. Audio quality and reduction of crosstalk are critical for us.
Thanks again.

Network Chatter!
I've got a problem with a samba installation performed by another user so
details of the installation are not known but hopefully someone out there
has run into the same problem and can give me some information on a possible
fix.
One of our Samba servers seem to be doing a significant amount of crosstalk
with a couple of our other Windows NT servers, I haven't been able to

unexpected behavior of trellis calls inside a user-defined function
I am making a battery of levelplots and wireframes for several fitted
models. I wrote a function that takes the fitted model object as the
sole argument and produces these plots. Various strange behavior
ensued, but I have identified one very concrete issue (illustrated
below): when my figure-drawing function includes the addition of
points/lines to trellis plots, some of the

Hi Jean-Marc,
Thank you. Yes, we do need both channels independent. So, if we encode each channel separately, we will be sacrificing the compression ratio we would achieve with stereo encoding, correct?
So, based on what you say here is my understanding. Please confirm this is correct or not:
1) If we use fec, we can reduce cross-talk but increasing bitrate. However, that should result in

Re: tdm400p static - out of ideas (Jorge Mendoza)
Ryan, from the console what does "zap show channel 1" or 2/3/4 in your
case say.
I have X100P's and I seem to be having similar sounding problems. I
noticed that the above command shows the channel to be off-hook at all
times when a phone line is plugged in.
I don't know why or if it is a bug in the application reporting the status.

[LLVMdev] Being able to know the jitted code-size before emitting
Hi everyone,
vmkit requires to know the size of a jitted method before emitting the
method. This allows to allocate the correct size for the method. The
attached patch creates this functionality when the flag SizedMemoryCode
is on.
In order to implement this functionality, i had to virtualize some
MachineCodeEmitter functions.
Is it OK to commit the patch?
Thanks,
Nicolas

Live Webcast in OGG
Hi,
Is it possible to stream live, as opposed to recorded, OGG format yet? I
had a look at the Icecast 2.0 beta instructions and it ends in a program
called "example" which will stream a pre-recorded OGG file to the
server. Is there anything to stream directly from the soundcard yet? If
not, is there anything in the pipeline?
If it is possible, what bitrates in mono/stereo are

Channel bleedover?
Occassionally on calls we get what sounds like low volume channel
bleedover. Not clear enough to make out words, but not echo of either
side of the main coversation. We're using a Digium card with 11
channels connected to PSTN lines. Any ideas on what the problem is or
how to go about troubleshooting?
Thanks!

I add a new pass with addSimpleCodeEmitter, with the emitter being a
SizeEmitter. Since the target calls the emitter with functions such as
writeByte, writeWord, etc.... the SizeEmitter class implements these
function by incrementing a counter.
At the end of the pass, the code size of the

Cisco 7960 lockups - any experiences?
This is almost certainly not an Asterisk-specific posting, but due to
my inability to find a VoIP-focused Cisco list, I'll post here in the
hopes of finding a more diverse user community.
I am using a Cisco 7960 (version 6.0 SIP firmware) with Asterisk, and
have been experiencing situations where the phone locks up. "Locks
up" means that the bottom part of the screen
